Poland plans to create a 200-meter-wide buffer zone along its state border with Belarus, Prime Minister Donald Tusk said on May 29.
The announcement came after a Polish border guard was left in critical condition after being stabbed through the existing fence with a makeshift spear the previous day. The attack was reportedly carried out by a migrant who was attempting to illegally cross the border.
The attack was not the first violent incident at the border.
Tusk said that a decision on the buffer zone, which was previously implemented under the previous government in 2021, would be made at "the beginning of next week."
Following the full-scale invasion, Poland's relations with Russian ally Belarus have deteriorated. Warsaw has also long accused Belarus of deliberately pushing migrants into Poland in order to pressure the EU over sanctions, a charge Belarus has denied.
Tusk announced earlier in May that Poland plans to invest 10 billion zlotys ($2.55 billion) in strengthening its borders with Russia and Belarus to deter potential aggression.
The prime minister first mentioned his plans to fortify Poland's entire eastern border with Belarus due to a growing "hybrid war" and illegal migration on May 11.
